Peracle reticulata (d’Orbigny, 1835)
Worldwide warm waters. Epipelagic.
Predator on zooplankton. Original taxon: Atlanta reticulata. Synonyms: clathrata, physoides, recurvirostra
 
This is the first species described in this genus; it is therefore not surprising that d’Orbigny chose the epidermis pattern as the distinctive feature. In fact, the shell of reticulata differs from those of the other species by a combination of characteristics: it is more slender than the other species, the rostrum is very developed, the whorls are separated from each other by a less incised suture than in diversa, the spirals are minute and not strong and large as in valdiviae, the last whorl is not adorned with a strong keel as in moluccensis, the microsculpture is very weak… But the lip is, as in the other members of the genus, very often damaged, even in living specimens. – 500m deep, off Murcia, S. Spain. 3mm.
The early whorls with some preserved periostracum.
In the Gulf Stream, off Fort Pierce, E. Florida.

It can happen that the reticulation goes further along the spire than it did in the previous pictured specimens. This shell (2,4mm) comes from 600m deep, Dubrovnik, S. Croatia, and, according to its author R. Stanić (HR), the mesh can be present « all around the shell »(CC BY-NC-SA). Notice the transition between two variants of the mesh: more or less squared on the anterior part to markedly rectangular on the last whorl.
